how to embed Coin3d window in Qt application?

No, all you have to do is define of the two, depending if you want to use SOQt as dll , or as static lib.

Either way, all you have to do is to open the project properties dialog ( in Visual Studio ), and add SOQT_DLL or SOQT_NOT_DLL to C/C++->Preprocessor->Preprocessor definitions.

And that's it. Should work fine now.
